It took one week and one day for the a-fib to return after stopping my Multaq. Darn it! I am 5 months post op. THought I might make it without the a-fib. Back to irregular heart beat and 120 beats a minute while resting. My a-fib must be lazy because it mostly happened when I am napping or sleeping. I called the doctor since I did not want to think about the ER. I was told to only go if I was over 130 beats a minute. He told me to start the Multaq again. He had mentioned ablation, so I am going to talk more about that with him. I don't want to stay on Multaq and warfrin for the rest of my life. Guess life would be pretty dull without my friend A-Fib! :smile2: At least it only lasted 15 minutes this time. Originally it lasted for days. Then for about 1/2 hour at a time, so I guess my heart is getting better. Pat
